ROBERT W. MANSON, OI PITTSBURGH, PENNSYLV EQLDER FOB STBOPPING Application filed. January 28, 1923. Serial No, 61-35%.

To whom c'tmay concern:

Be it known that I, ROBERT W. Manson, a citizen of the United States, and residin in the city of Pittsburgh, in the county 0 Allegheny and State of Pennsylvania, have invented or discovered a new, useful, and Improved Holder for Stropping Razor Blades, of which the following is a speci fication.

My invention consists in a new and improved holder for use in stropping razor blades.

More particularly my holder is intended for razor blades of the Gillette type, which have two cutting edges and are, provided with perforations disposed along the longitudinal axis of the blade.

One of the objects which I have in view is the provision of a ractical blade holder which will present bot cutting edges of the blade for stropping.

holders with which I am familiar, present but one edge of the blade at a time for stropping,

and after one edge has been stropped, the blade must be removed from theholder and remounted therein in the reversed position before the other edge may be stropped.

Another object which I havein view is a provision of a holder in which the blade may be mounted and from which theblade ma be dismounted quickly and conveniently, and which will present the blade to the strop at the proper angles for efiicient strop- F or these and other purposes, I have invented a holder having the following characteristics. Theholder comprises two main elements or levers which for convenience I term the base and the cap, and between which the blade is resiliently clamped. In the preferred form of my invention shown in the drawings, the base and cap are disface to face and are intermediately connected in such a manner as to oscillate or rock in relation to-each other, so that either pair of ends may be compressed together or spread apart. Between the handle ends of the members I inter-pose means which act to normally compress the blade engaging ends together to hold the blade in place, said last mentioned ends being spread, to permit the insertion or removal of the blaadse, by compressing together the handle en I have also provided means for reventing lateral movement of the blade while mounted in the holder, such means being illustrated as studs projecting from one of said members and extendin through the perforations in the blade into perforations or sockets in the other member. 7

Means are also provided for maintaining the members in proper alinement.

I also provide means for presenting the.-

blade at the lplmper angles to .the surface of the strop. us the outer faces of the base and cap are provided attheir blade 'engag-. mg ends with oppositely inclined surfaces, which, by surface contact with the strop,

present the cutting edges of the blade at the proper angle for stropping.

Other novel and useful features of construction and arrangement ofparts will appear from the following description.

In the accompanying drawings, which'are merely intended as illustrative of theprinciples of my invention, Fig. 1 is a perspective of a holder with a razor blade mounted therein ready for stropping; Fig. 2 is a side or edge view of the same, and Fig. 3 is asimilar view, without the blade, showing the handle ends compressed together read for the insertion of the blade between the lade e aging ends.

he following 1s 'a detailed description of the drawings.

The holder, as illustrated, is of the following construction.

A and B rep-resent the two main members,

the base and cap, respectively. Said members are in fact a pair of levers formed of metal bars having flat abutting surfaces. Intermediate of their ends, preferably nearer their handle ends said base and cap are hinged or connected together in such a manner as to permit oscillation or rocking in relation to each other. Thus I have shown a headed screw 1 extendin%through a loosely fitting hole 2 in the cap a threaded hole in. the base A, play beingand' screwed into provided between the two members, as,

shown.

The handle ends of the cap and base, the

right hand ends in the drawings, arenormally held s read apart by resilient means, such as the ent leaf spring C interposed between the same. Toprevent the members A and B from swinging out of mutual alinement, I provide means, such as the stud 3 on P5113116 cit;

be said e hiss A which i i ages the socket d in the 0 hold the spring C in spring may .exten tween the cap and base, and be perforated for the protrusion through the same oi? the screw 1 and the stud 3.

It is evident that the blade enga ing ends of the base and cap, the left han ends in the dra are resiliently clamped together. To enable the said ends to assume when com r toether prefer to d the sai end of te cap upwardly, as shown in Figs.- 2 and 3, the s ht angle being at 5.

e blade engaging end of the base is position, the tail rovided with means for anchoring the; a

lads in ppsition, Thus the studs 6 are provided, w ch studs extend through the per:

forations of the blade l), and when the blade engaging ends of the base and cap are compressed together, the ends of said studs protrude into the socket holes 7 in the cap :8. Said studs are short enough to clear the cap when the holder is 0 ened tor the insertion or removal of the bl ade to give the necessary clearance as shown in Fig. 3.

It is evident that when the handle ends of the base and cap are compressed together, the opposite ends are sprea apart, as shown in F1. 3, thus permitting the insertion of the bade D which is laid on the base with the studs 6 extending up through the perforations of the blade. The handle ends are then allowed to spread apart, under the influence of the spr C, and the blade is clamped in the holder as shown in Figs. 1 and 2. en the blade has been suficiently either operation. Thus both stropped, the handle ends of the base and om ressed together and the blade may be out of the holder.

It is evident that both cutting edges of the blade are exposed for strapping. The user first lays one member of the holder, the cap or base, on the stro and moves it back and forth, properly tilting or roc the same to bring first one edge and then t e other edge of the blade against the strop. He then turns the holder over and lays the other member of the holder against the strop and repeats the stropping sides of both. edges 0 the blade are strop ed without removing the blade. from the holder.

To insure the proper angle of application of'the beveled edge of the blade to the strop, I provide the outer faces of the blade enga 'ng ends of the base and cap with op-' pose inclines or beveled surfaces 8 meeting at the longitudinal axis of the member which are alternately in surface contact with thestrop as the holder is moved ,back and forth in stropping, the ridge 9 formed the intersecting inclines being the axis f -'versa l at the end of a stroke.

forwardly be-' I B y tion of the ainder dent that'it may be designed to accoo- 7 date any type of double edge razor blades, such as" Durham blades.

llt is further evident that my invention may be readily adapted for stropping single edblades, if so desired. 7

at I desire -to claim is 1. A stropping holder for razor blades comprising a pair of lever members movabl connected together intermediate of their en s so as to oscillate in relation to each other.

one pair of ends being compressed together while the opposite ends are spread apart and vice versa, one pair of ends acting to grip the razor 'blade between them, while the major portion of the remainder is used as a handle for the holder, the longitudinal axis of the blade being longitudinal of the axis of the holder, and resilient means for normally maintaining the blade gripping. ends compressed together and the handle ends spread apart whereby the razor blade is clamped in the holder for stropping and by compressmg together the handle ends said blade grip mg ends may be temporarily spread apart for the insertion or removal of a razor blade 2. A stropping holder fdr razor blades comprising a pair of lever members movably connected together intermediate of their ends so as to oscillate in relation to each other, one pair of ends being compressed together, while the opposite ends are spread apart and vice versa, one-pair of ends acting to grip the razor blade between them, while the major portion of the remainder is used as a handle for the holder,
